Linear Labs is a technology company.
Linear Labs develops patented high-torque motor systems and integrated electrification solutions that incorporate advanced controllers and high-performance software. The company's core technology, the Hunstable Electric Turbine (HET), underpins its offerings, which are designed to significantly improve motor efficiency and performance across various applications. Their approach focuses on a novel motor design to enable superior power and torque density.
The company was founded by Brad Hunstable and his father, Fred Hunstable, with Fred serving as the inventor and CTO, and Brad as the CEO. Brad Hunstable, known for his work in pioneering live streaming technology, joined his father in a shared vision to fundamentally reinvent electrification. This father-son collaboration emerged from Fred's inventive work in motor design, leading to the formation of Linear Labs to commercialize this innovation.
Linear Labs' products serve a diverse range of industries, including wind energy, nuclear power, pumps, actuators, and defense. The company aims to advance smart motor manufacturing capabilities and stimulate technological growth by providing its proprietary motor technology. Their long-term vision positions them at the forefront of what they term "Electrification 2.0," striving to establish new benchmarks for motor system performance globally.

# Linear Labs: High-Level Overview
Linear Labs is an electric motor technology company developing next-generation electrification systems for vehicles, HVAC, robotics, and industrial applications.[1] Founded in 2014 and based in Fort Worth, Texas, the company has raised $27.75M in funding (most recently $17M three years ago) and currently operates with approximately 36 employees.[1][2] Linear Labs addresses a fundamental inefficiency in global energy infrastructure: 45% of the world's electricity passes through electric motors, yet motor designs have remained largely unchanged for over a century.[4] The company's core offering is an integrated system combining proprietary high-torque motors, intelligent controllers, and dynamic software that delivers 2x the torque and 30% greater efficiency compared to leading competitive motor systems.[3][5]
The company serves a broad market spanning electric vehicles, light electric mobility (e-bikes, scooters, motorcycles), HVAC systems, robotics, and industrial machinery. Its HET Light Series motors are specifically engineered for lightweight applications, promising up to 40% lower electrical consumption and up to 100% increased range in micro-mobility devices.[5] With a revenue profile under $5 million, Linear Labs remains in growth phase, positioning itself as a critical infrastructure player in the electrification transition.[2]
# Origin Story
Linear Labs emerged in 2014 during the early stages of the electric vehicle revolution, when the limitations of conventional motor technology were becoming apparent to engineers and entrepreneurs.[1] The company's founding reflected a recognition that electrification's success depended not on incremental improvements to century-old motor designs, but on fundamental physics breakthroughs. The company has since filed 73 patents across electrical engineering, electrical generators, and energy conversion, establishing a robust intellectual property foundation.[1] Early traction came through partnerships and development agreements with OEMs across automotive and industrial sectors, validating the market need for higher-efficiency motor systems.[1]
# Core Differentiators
Linear Labs' competitive advantages center on three integrated dimensions:
The company's integrated approach—combining superior hardware with intelligent software—distinguishes it from competitors focused on single-component optimization. Linear Labs emphasizes manufacturability and modularity, suggesting a path to volume production that many advanced motor startups struggle to achieve.[3]
# Role in the Broader Tech Landscape
Linear Labs operates at the intersection of three converging mega-trends: electrification of transportation, industrial energy efficiency, and the Internet of Things.[4] The company's timing is strategically advantageous. Global electric vehicle adoption is accelerating, HVAC systems account for significant building energy consumption, and industrial motors represent untapped efficiency gains. The fact that 45% of global electricity flows through motors creates an enormous addressable market for efficiency improvements.[4]
The company influences the broader ecosystem by demonstrating that legacy motor technology can be fundamentally reimagined rather than merely optimized. This challenges incumbent motor manufacturers and validates the venture-backed startup model for deep-tech hardware innovation. Linear Labs' focus on sectors spanning transportation, buildings, and industrial applications positions it as infrastructure-level technology rather than a niche solution.
# Quick Take & Future Outlook
Linear Labs faces the classic deep-tech challenge: translating laboratory breakthroughs into manufacturing scale and market adoption. The company's Series A funding status and modest revenue suggest it remains in the commercialization phase, with the critical next milestone being volume production partnerships with major OEMs in automotive and industrial sectors.[1][2] Success will depend on converting proof-of-concept agreements into long-term supply relationships and demonstrating that superior efficiency translates to customer cost savings or performance gains that justify adoption.
The broader tailwind is undeniable: electrification is non-negotiable, efficiency improvements reduce operating costs, and the 100-year stagnation in motor design creates genuine opportunity for disruption. If Linear Labs can scale manufacturing while maintaining its performance advantages, it could become foundational infrastructure for the electrified economy—the kind of enabling technology that operates invisibly but powers everything from delivery vehicles to climate control systems. The next 3-5 years will determine whether the company becomes a critical supplier to major OEMs or remains a specialized solution for niche applications.
Linear Labs has raised $28.0M across 3 funding rounds. Most recently, it raised $17.0M Series A in March 2022.
